SiC FETs offer silicon substitution to cut losses in power systems
Manufacturer of Silicon Carbide (SiC) power semiconductors,UnitedSiC has announced the UJ3C series of 650V SiC FETs as drop-in replacements for silicon Superjunction MOSFETs. Available in standard TO-220, TO-247 and D2PAK-3L packages, they operate with standard Si-MOSFET gate drive, eliminating the need to re-design drive circuits, while offering low RDS (ON) and low gate charge to reduce system losses.
Ceramic capacitors feature high ripple current capability
KEMET has expanded its commercial and automotive grade high voltage C0G Ceramic Capacitors as increasing use of wide band power semiconductors in power electronics applications drives forward new inverter and DC/DC converter designs with far greater power density, voltage, current and frequency.
Tech enables higher power densities in smaller form factors
Global supplier of electronic components, KEMET, has announced new patentedKONNEKTtechnology enabling high power density by combining multiple components into a single surface mountable package. This technology is designed for use by power electronics engineers where high-power density in a small form factor is critical.
A zero-power receiver for touch communication
Battery lifetime is an important issue in wearable devices. Ideally, they should always be ready to receive control signals without consuming a lot of power. Researchers at ETHZurich have now developed azero-power receiver for touch communication that harvests its energy directly from the signal.Having electronic gadgets always ready to function at our command comes at a cost.
Ceramic capacitors meet wide bandgap semiconductors trend
Commercial and automotive grade high voltage C0G Ceramic Capacitors from KEMET have been extended as increasing use of wide band power semiconductors in power electronics applications drives forward new inverter and DC/DC converter designs with far greater power density, voltage, current and frequency.
Electrolytic capacitors meet challenging applications
Now available in Europe through TTI are ALS70 and ALS80 series high CV screw terminal electrolytic capacitors from KEMET. The products are ideal for use in frequency converters, uninterruptible power supplies (UPS) and switch mode power supplies (SMPS) in challenging electrical and environmental applications including rail.
Aqueous storage device can be charged in less than half a minute
A KAIST research team developed a new hybrid energy storage device that can be charged in less than half a minute. It employs aqueous electrolytes instead of flammable organic solvents, so it is both environmentally friendly and safe. It also facilitates a boosting charge with high energy density, which makes it suitable for portable electronic devices.
Fully encapsulated dual power modules offers high power density
Renesas Electronics has announced two new fully encapsulated digital DC/DC PMBus power modules that deliver the highest power density and efficiency in their class. The dual ISL8274M operates from a 5V or 12V power rail, provides two 30A outputs and up to 95.5% peak efficiency in a compact 18x23mm2 footprint.
Package designed to provide turnkey solution for ferrous target
A new package offering for its wheel speed sensor product family has been announced by Allegro MicroSystems Europe.The package includes an optimised Hall-effect integrated circuit (IC), rare-earth pellet, and high-temperature ceramic capacitor in a single overmoulded package.The fully integrated solution reduces the need for external EMC protection and integration of a magnetic circuit, reducing manufacturing complexity.
Switch generates short pulses for precise measurement
At this year's Photonics West show, taking place 30th January to 1st February in SanFrancisco, LASER COMPONENTS presents QuickSwitch - a hybrid 905nm high-power PLD generating what the company claims to be the world's shortest pulse width of 2.5ns typical at a pulse frequency of up to 200kHz. It can be equipped with various storage capacitors, depending on which, it achieves an optical peak power up to 89W. The pulse width of the optical output d...
